HENRY T. BEAM, OF PALESTINE, ASSIGNOR OF TWO-THIRDS TO WILLIAM C. JONES AND A. P. XVOODVVORTH, OF ROBINSON, ILLINOIS.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 318,591, dated May 26, 1885.

Application filed November .22, 1884.

To all whom, it may concern.-

Be it known that I, HENRY T. BEAM, a citizen of the United States, residing at Palestine, in the county of Crawford and State of Illinois, have invented certain new and useful Improvements in Oar-Couplings, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to car-couplings; and it consistsin certain improvements in the construction of the same, hereinafter described, and specifically set forth in the claim.

Like letters represent like parts in both I 5 figures.

Figure 1 is a longitudinal section of my improved coupler, and Fig. 2 is a plan view of the same.

In the drawings, A represents the drawhead. It is provided with a vertical slot, to,

for the insertion from the top of a hookshaped coupling-pin, B. This hook-shaped pin 13 is provided with a beveled lip or projection, 13, at the fore end, to engage under a shoulder, A, formed within the mouth of the draw-head, and prevent the escape of the pin B.

Within the bottom of the opening o the draw-head is a shoulder, A with its down ward side parallel with the face of the hooked pin B, so that when cars are coupled and in motion the hooked pin fits snugly against the inner faces, A A, of the draw-head, and the lip 13 acts as a key to hold the pin locked in 5 position.

The rear end, B, of the pin B is rounded, and fits loosely in a groove, A, at the inner end of the chamber of the draw-head, and is provided with an overhanging shelf, A that (No model.)

prevents the pin from jumping out of the draw-head.

Within the funnelshaped bottom of the draw-head is a small hole, a-, to allow rain or melted snow to escape.

b is a chain used in raising the pin for uncoupling from the top of a car, and G is a key mounted upon a rod, O, pivoted in bearings passing through the draw-head. This rod has a handle at each end, by which means the key is easily operated from the sides of the car.

0 is a rest projecting within the groove a, to keep the free end of the key upward and out of the way of the incoming link D.

The pin 13 can be easily removed from the draw-head, as it is not attached thereto.

I am aware that car-couplers have been provided with a hooked coupling-pin having its rear end mounted upon a transverse rod, and a pivoted arm placed thereunder to lift it, and that the hooked pin of others has been placed loosely within the draw-head and made to hear at its front and rear end against shoulders therein, and I do not claim, broadly, carcouplers having the above construction.

Having fully described my invention, what I claim is- The combination of a hook-shaped pin, 13, lying loosely within a draw-head, a key, O, pivoted to the draw-head under the pin B, and a draw'head provided with a rest to support the key, substantially as and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.
